The Hanyusuchus is known from Chinese reports and decrees. It was bigger than the endangered Chinese alligator which still lives in the same area. During the Three Kingdoms Period the 200’s it was reported the Hanyusuchus were kept in moats around castles in Wuzhou. Criminals in those areas were fed to the crocodiles. Reports from the 300’s show that Hanyusuchus were killed and their heads were displayed by the river as a warning to other crocodiles in the area. In 819, Chinese poet and politician Han Yu (for whom this crocodile was named), decreed that the crocodiles needed to “leave or be killed” after several attacks at Bad Creek on the Han River. In 999, a ten year old boy named Zhang was killed. Chen Yaozuo publicly announced the crocodile’s crimes and ordered troops to capture it with nets and ropes made of horsetail hair. Another “punishment” decreed against a dangerous crocodile in Hanjiang was to spread calcium oxide in the river, poisoning it. In the 1600’s wine and sacrifices were given to the remaining Hanyusuchus on Hainan Island. The last confirmed report of a Hanyusuchus was on Hainan Island in Crocodile Cave in 1630. Although Jurassic Park is fiction, scientists are working on several de-extinction projects. In fact, in 2003 scientists did bring back the extinct Pyrenean ibex, a type of wild goat, for 7 minutes before it died, showing de-extinction is possible. The Hanyusuchus would not be a good candidate since there are no known specimens of soft tissue. If the Hanyusuchus was brought to life, could it ever be reintroduced to its native homeland in South China? With a population over one billion, China’s urbanization has had a negative impact on many species like the endangered red panda or the extinct baiji. There are many organizations focusing on protecting habitat and species in China, most notably the giant panda which as of 2016 was downgraded to “vulnerable”. If the Hanyusuchus were brought back to South China, would it be able to survive along the populated waterways?
